Abstract
We discuss a supersymmetric inflationary cosmological scenario in which inflation takes place after GUT breaking but before SUSY breaking. The framework is within N = 1 supergravity with the inflation and SUSY breaking sectors hidden from one another. We present a specific one-parameter inflation sector coupled with F-type SUSY breaking, with more than sufficient entropy release. Adequate baryon asymmetry is produced by an out-of-equilibrium decay mechanism in spite of a low reheat temperature. The condition that the gravitino abundance should not affect nucleosynthesis fixes the single parameter and the resultant density flucctuation to be of O(10 −4). If gravitinos are stable their resulting abundance is sufficient to account for the dark matter.
